1 A horizontal line passes through the
point (0,4). A vertical line passes
through the point (-16,0). What is
the intersection of the two lines?

Given:

A horizontal line passes through the  point (0,4).

A vertical line passes  through the point (-16,0).

To find:

The intersection point of these two lines.

Solution:

A horizontal line passes through the  point (0,4). It means the y-coordinate of each point on the line is 4 and the equation of the line is

A vertical line passes  through the point (-16,0). It means the x-coordinate of each point on the line is -16 and the equation of the line is

So, the coordinates of the intersection point of these two lines are (-16,4).

Therefore, the required point is (-16,4).
